Project Description:
I have a matrix keyboard circuit using Atmel AVR32UC3L064[1] microcontroler and mechanical keys connected to microcontroler's GPIO pins.

Schematics will be provided to selected developer.
Using Nut/OS RTOS[2] is a big plus.

The firmware must:
- Read keypress from keyboard (GPIO pins)
- Convert read key to specific PS/2 scancode and transmit using bitbang PS2 interface. (Sample implementation of bitbang PS2 interface can be provided)
- Clean and maintainable code.
